The DataDashboardItem.DataSource property can now be set to null by the Dashboard Designer.

Please make note of the following if you work with data sources via application programming interface.
Previously, if a dashboard was assigned to the Designer, the DataDashboardItem.DataSource properties of its items could not be set to null automatically, so that you did not need to check for this when you accessed the data source from code.
Starting from the 13.1.6 version, the DataDashboardItem.DataSource is automatically set to null for dashboard items that contain no data items or whose data source has been deleted.
